**Some readers asked about the creatures on last chapter and I think that maybe I didn't wrote that right on the other chapters, so I'll explain now... Natasha was remembering how Bucky helped her to escape from Ivan, and she described there about how creatures from Thano's army arrived on earth and started to assume people's form and caused the population to live on bunkers, always hidden... So, those creatures was what they were talking about on last chapter, and yes it looks like an apocalipse zumbi, but they're aliens, that can look like humans... I hope you all can understand now, that's the reason everybody lives on a bunker now.**

Is he kissing me or am I kissing him? Why am I doing this? I didn't kiss him, he kissed me. Natasha thought as she slowly opened her lips, so that Steve would place his tongue between her lips.

Natasha took a deep breath and when she felt the tip of his tongue touching her lower lip, she let out a short moan of satisfaction.

I thought I would never feel his breath in my mouth like that again. Why is it still so good to feel that? To feel him? Natasha thought as she discreetly turned her body toward Steve, who was now sliding his tongue into Natasha's mouth.

What is he thinking right now? Natasha wondered, as she corresponded to Steve's tongue caress in her mouth.

Natasha moved her tongue over Steve's and he took the opportunity to suck her tongue to inside his mouth.

It was supposed to be a delicate and subtle move, but Natasha eventually let out another low moan directly to Steve's lips, which triggered him. Steve sucked her tongue harder, which made Natasha put her hands on his shoulder and tried to pull her tongue back.

As Natasha pushed Steve's shoulders back to loosen her tongue, Steve lost his balance and fell backward onto the floor. Natasha ended up falling over his body, since she was leaning over him with her hands on his shoulders.

Before Steve could open his eyes, Natasha pressed her lips to his again and slipped her tongue into Steve's mouth and stroked the full length of his tongue.

Natasha explored every corner of Steve's mouth. It was a mixture of abstinence with dominance and anxiety that made her massage his tongue constantly and even touch the palate of his mouth with the tip of her tongue.

Steve put both hands on Natasha's waist and squeezed tightly. One part of him was wishing to push her away, but the dominant part made him press her body against his.

Natasha placed both hands on Steve's face, as she kissed his mouth infinitely. Steve slid a hand from Nat's waist to her back, then with the same hand he slid down, until he felt his hand filling one of her buttocks and squeezing it hard.

Natasha didn't complain about this, on the contrary, she shrugged slightly, leaving her crotch region, just above Steve's hip. Steve immediately forced himself to sit again, without stopping the kiss and without taking his hand off Natasha's butt.

As they sat down, Natasha slid her hands from Steve's face to his defined pectoral; she lowered her hands a little more and grabbed the hem of his shirt. Natasha lifted Steve's shirt and dragged her nails through Steve's belly as she finished lifting and removing his shirt off.

Natasha had to interrupt the kiss to take Steve's shirt off. She didn't want to stop the kiss, fearing that he may regret and stop what they are doing and she needs so much to have him now, she misses being in touch with his body, that single night a few years ago, had been very little for her.

As soon as Natasha finished removing Steve's shirt, she looked at him and waited for his reaction and for Natasha's surprise, he didn't stop, he put his other hand on the button of Natasha's pants and unbuttoned it, very easy, which made Natasha a little annoyed by his ability on removing woman's clothes that easy with just one hand... Natasha wonder how many times he and Sharon must have done it for him to become such an expert at undressing bodies. And yes, she still feels jealous of him.

Natasha didn't have time to be angry or to think about giving up... She lost her breath when she felt Steve's hand slide the zipper of her pants down and then his fingers down her panties, strumming her clit at the correct intensity.

Steve had his face and neck completely red as he watched the expression of pleasure on Natasha's face, and even when she tried to glue her body on his, to kiss him again, he didn't allow it, he wanted to watch her.

Natasha understood and gave a small, almost imperceptible, smile.

Natasha got rid of the jacket she was wearing and then got rid of her blouse.

Steve looked directly at Natasha's bra and bit the tissue that connected one bulge to the other. Steve bit into it and tried to pull it off, which made Natasha laugh and make Steve irritate with her bra.

Steve decided to put his hands on her bra and rip it off.

Steve had to stop for a few seconds, just to stare at Natasha's breasts, as if it were the first time he'd seen them. Well, it's the second, so he's still very impressed.

Maybe the other time, he didn't pay so much attention, but now he is, and this look of desire, I recognize in any man. Natasha thought as she smirked, extremely pleased to see that she still had a big effect on Steve.

Steve put a hand under each of Natasha's breasts and lifted them, then joined them and squeezed tightly one against the other. Natasha groaned as she watched Steve's tongue run through her nipples, almost at the same time.

Steve could feel Natasha's nipples stiffening with his tongue. Steve gave hiccups alternating between one nipple and the other, causing more moans from Natasha's lips, who started to move her hip back and forth, as she felt Steve's erection pulsate beneath her.

Natasha just screamed when Steve bit her nipple hard. Steve stopped at the same time and looked into her eyes, startled.

Natasha was panting and she shook her head.

S: Did I hurt you?

Natasha shook her head.

N: I don't... I don't like teeth...

Steve nodded and lifted his face to Natasha's, she pressed her lips to his and they explored each other's mouths again.

Natasha unbuttoned Steve's pants and slipped her hand inside his pants and noticed that he wasn't wearing any underwear.

As soon as Natasha's hand touched his cock, Steve grunted and released her breasts to grab Natasha's buttocks again and press her body against his. Natasha pulled Steve's rigid cock out of his pants and smoothed it steady, which made Steve bite Natasha's bottom lip.

The moment Natasha prepared to get up to take off her pants, Steve's W.T. started to peck. They both stopped the kiss, but remained with their lips glued. They both opened their eyes and then frowned. Who could it be? They both thought.

What was very strange and unusual was someone calling the W.T from someone, who's on a mission out of the bunker, there is a huge risk of calling attention of those terrible creatures who take on human forms. If someone is calling it's because it's an emergency.

The first thing Natasha thought of was James and that something would have happened to him and Steve thought it would be some emergency with Sharon and her pregnancy.

N: James! You have to attend!

Steve nodded and picked his W.T as Natasha stepped off him.

Steve looked at the viewer who was calling.

S: It's Sharon.

Steve looked at Natasha and made negative with his head.

S: I'm sorry, I need to answer.

Natasha took a deep breath and tried her best to pretend she didn't care, she nodded and searched for her clothes while Steve got up and adjusted his pants.

Steve walked around the room so he could speak to Sharon.

Steve answered the call.

S: Sharon?

A silence followed, which distressed Steve.

S: Sharon? Is that you? Are you all right?

Sharon: Yes.

Again a silence.

S: What happened?

Sharon: I shouldn't have called.

S: Why? Is it something with Maggie?

Sharon: No... No. No. She's fine. I just wanted to hear your voice.

S: Sharon...

Sharon: I know it should only on emergency, but we got into a fight these days... I've been in a strange mood and I should have said goodbye before you left, I'm sorry for ignoring you so much. I miss you.

S: It's okay... I miss you too.

Sharon: Get home safe.

S: I will.

Sharon: Good night, my fiancée.

Steve could hear Sharon small laugh when she called him that, but the mood between them was still strange, it could tell by the heavy atmosphere that was when they had nothing more to talk to each other.

S: Sharon? Is James, okay?

Sharon: Uhm... I think so.

S: Do you think so?

Sharon: Well, I didn't see him, Clint is with him.

S: But you know that all the kids got sick, James is my son, so...

Sharon: I know he's your son, I'll check on him. If he's okay, I'll ring twice to your W.T. Ok?

S: Yes, I appreciate that.

Steve ended the call.

Steve stopped in the hallway and took a deep breath, he put his hand on his forehead and felt a huge remorse for betraying Sharon, and this time there is no doubt that it was betrayal because they're engaged. He never knows why he can't resist Natasha, he loves Sharon.

Before Natasha showed up at the bunker, Steve and Sharon's relationship seemed different from what is now, like when they announced they were getting married... They were all smiles, caresses and support, but since Steve discovered to be James's father, the jealousy and fear of Sharon increased absurdly, and she had never shown jealousy or fear of losing him.

In fact, the only person Sharon was afraid of losing Steve to, was Natasha, but this before they started to date, and just because Steve and Natasha used to work and had fun together all the time, but that was a long time ago, before the Civil War.

When Natasha disappeared in the world, there was no more threat for Sharon, and Steve was genuinely in love with her and willing to marry her and live with her forever. Nothing more was a reason for them to fight.

Neither Sharon nor Steve know exactly how they started to move away from each other, they just know that it was after Steve know about being James' father. When the night came, at the time of intimacy, Sharon deviated from all his touches and during the day, she avoided him or they started to argue about anything. The only moment of respite was when it came to dealing with matters relating to their daughter.

Steve looked at the entrance to the room, where he had left Natasha. What to tell her? It wasn't for that to happen, I honestly don't know why I kissed her, I don't think of her like that, what were we doing? What did I do? Steve inquired himself, not having the courage to walk into the room and face Natasha.

Am I going to hurt her? She doesn't love me, so she won't be hurt, maybe angry. I just have to apologize. What was I thinking? I only love one woman and she's there in the bunker, waiting for me with my daughter in her belly.

Steve concluded, taking another deep breath and walking into the room. Steve looked at his shirt on the floor and then looked for Natasha and didn't find her.

S: Nat?

Steve called her and got no answer, he saw that the room had one more door at the other corner and walked there. The door was open and the room was probably a waiting area as there were three sofas and a desk.

Natasha was lying on one of the sofas, sideways, facing the back of the sofa. Steve couldn't get into the room, he almost turned to walk away and to not to have face her.

N: You can sleep on the other couch, it's better than the floor.

Steve looked at her and wanted her to turn and look into his eyes and say something, but she remained motionless. Steve stepped into the room and lay down on the couch facing Natasha's.

Apologize!!! What are you doing? Apologize! Steve screamed at himself in his mind, but he looked at Natasha and his lips seemed sealed.

That is so wrong. Why did you do this to them? It's not fair! Steve wondered and couldn't close his eyes, he spent hours looking at Natasha lying down.

I've never felt so strange in my whole life. Why do I care so much about you, Natasha? Why? It was Steve's last thought, before he finally fell asleep.

As soon as the dawn came, Natasha got up and approached Steve on the couch.

N: It's time.

Steve opened his eyes in alarm and sat down. Natasha turned away and walked to the room door. Steve watched her.

S: Natasha?

N: No, Steve. No need. Don't say anything.

S: But...

N: I understand that it was a fragile moment of the two of us... Again... It was wrong, I'm glad it didn't go until the end.

Steve didn't try to argue, he was even relieved that Natasha wasn't angry, sad or feeling used... Steve soon thought they are friends and this closeness between them can sometimes be confused with something else and that's why they had that moment last night. But how to know if it's a usual thing for friends to have moments of desire as strong as what they felt last night and that night in the hotel room in Germany?

The two of them left the building and advanced for hours until finally finding an abandoned hospital.

N: No matter what you see, we can't help these people... Many of them seek help in the hospital, but most are just fooling us.

S: So there's a minority who could still be health and...

N: Yes.

S: We can't leave them behind.

N: We can and we will, we have a single mission here and I really want to go back to my son as soon as possible.

S: He's fine.

Natasha looked at Steve.

S: I asked Sharon to check him and she said she'd give me two rings to confirm that he's okay. When we woke up, I checked my device and she had given.

Natasha nodded.

N: Still, I'm feeling something wrong.

S: About this hospital?

N: About James.

S: You're just missing him.

N: Probably. Let's finish this.

...

Tony: Dr. Cho, did you want to talk to me?

Cho: Yeah, Tony, it's about this kids epidemic.

T: I'm very worried about that.

Cho: Me too.

T: I hope that Steve and Natasha will be back soon with these vaccines.

Cho: Tony... Have you ever stopped to think how those children got sick?

T: I imagined that some virus was through the air and it arrived here.

Cho: That would be very unlikely. We live enclosed here and this virus needs a host.

T: Do you think someone brought the disease in here, then?

Cho nodded.

T: But it's been months since we got new people... Do you think any mutants brought this disease?

Cho: They didn't bring any children with them, and we know that this disease is only reaching children.

T: So there is no one else who could have brought this disease here.

Cho: Yes, there is.

T: Who? Do you mean Natasha?

Cho: Her son.

T: He is not sick.

Cho: He had a fever before the epidemic starts, I believe the virus hasn't been able to penetrate his system but that he may be transmitting to the other children.

T: Are you sure it's James?

Cho: No, I would have to do more tests on him to be sure, the results wouldn't come out so fast and I'll need more blood samples to test.

T: He is very young, Cho.

Cho: He needs to be isolated.

T: No way, he is all shy with everybody, he cries too much wanting his mother, he won't be in a room alone.

Cho: Tony, I'm almost sure it's him. We still have about ten children still healthy, but should we isolate ten just to protect one?

Tony frowned and sighed.

Tony walked across the room and then rubbed his forehead, reluctant to accept the idea.

T: I can't do that to him. I need to know the opinion of the others, someone who's close to the kid, like Clint.

Cho: He won't accept it.

T: Natasha will kill me and you and everyone here for allowing this.

Cho: She'll have to understand, Tony. I don't want to do this as much as you, but we have already lost eight children, we have thirty-two patients and five in serious condition.

T: I know, I understand you. I just need some time...

Cho: Okay, let me know what to you decide.

The only person Tony talked about that was Pepper Potts, because she's the only person who can somehow put some sense into his head.

T: I really don't want to do that, not just because he's the son of my friends, but because he's just a baby.

P: I understand, Tony. And I understand that is necessary that he be isolated for the safety of the other children, let Cho do the tests soon and eliminate him as the source of this disease. The sooner, the faster all this disorder goes away.

T: How do you think Natasha and Steve will react?

P: Bad. Very bad, but they will have to understand that the situation here is chaotic, we can't lose all these children.

Tony folded his arms and was silent for a long time. Pepper could feel the wrinkles of Tony Stark's jump over his forehead.

Pepper walked over to Tony and laid a hand on his arm, making him uncross his arms and then making him hug her.

P: Don't blame yourself, you're doing the right thing this time.

T: Are you sure?

P: Yes.

Pepper kissed Tony's cheek for a long time and hugged him tightly next.

...

At the end of the day, Clint arrived from work at his room.

As soon as he walked in, Clint walked over to the chair and sat down. Laura approached Clint, and touched Clint's shoulder.

Clint was hoping to get a kiss and a hug, as he received every night when he arrived, but Laura only touched his shoulder.

Clint lifted his face to look at Laura.

C: What is it, woman?

The concern on Laura's face made Clint get up from his chair immediately.

C: Our children?

L: They remain hospitalized, but they are still stable.

Clint looked around the room.

C: Where's the Cap-Baby?

L: They took him.

C: They? Who?

L: Tony and Dr. Cho came here and told that James who was infecting the other kids.

C: What the hell? The boy is not even sick!

L: Yes, they said it was some child who came from the outside who brought the disease in here.

C: What did they do with James?

L: They just told me that he would have to stay in isolation.

C: He's just a baby! He must be freaking out now without someone he's used to. I'm going to talk to Tony right now!

Laura was going to try to calm Clint, but he left the room, like a lightning, he went to Tony's room and slammed the door.

Tony opened the door.

C: Where's the boy?

T: He's fine, he's being treated well. I made sure of that,

C: WHAT AN ASS YOU ARE, STARK! You know damn well how James is with strange people, he must be terrified.

T: Clint, take it easy.

Pepper curled up in the robe and approached the door.

P: Do you want to see him?

Tony looked at Pepper and shook his head.

P: I think he'll feel better if he sees that James is fine.

C: Take me to him.

Pepper and Tony accompanied Clint to the elevator and down with him to the F-wing.

The F-wing was extremely cold, the air conditioning was much stronger there, the walls all white, and as if that wasn't enough people there were wearing special clothing like If they were dealing with chemical weapons.

C: What the fuck is this place???

T: Our research and medicine center. We store blood bank, laboratory and ward infectious diseases with isolated boxes to prevent propagation.

P: We have to wear this from here.

They arrived at the anteroom in the isolation area, the three of them donned the special clothes, put a mask on their faces and a cap.

Clint made negative with his head.

C: I don't believe that.

T: If we are not being decimated by diseases like the other bunkers, it's thanks to theses actions.

They entered the isolation area and Clint was surprised to see that more people were being isolated, he had no idea that such place existed there.

Clint looked at a pale blond girl in one of the paneled glass pews, looking straight at him.

C: What does she have?

T: I don't know.

C: Are her eyes bleeding?

T: Probably.

In the other box, a man seemed to be insane, shaking his head and beating desperately in the glass, trying to leave.

C: Oh my God, Tony.

T: He tried to eat his own children.

C: Is James here? How could you? How could you do that to him, Tony?

T: I put him in a separate room.

As they walked to the end of the hallway, Tony opened the door to a single insolating box.

Clint came in and could see a nurse in a special outfit like theirs and mask on her face near the cradle of James, stroking his back to try to calm him down, but totally in vain.

Clint approached the stall and was horrified tosee how much James was crying, despite the useless efforts of the nurse whotried everything to make him sleep.
